摘　　要：本文介绍了IEC 62439-3中的并行冗余协议(PRP)的基本原理,对PRP网络中双连接节点的基本结构以及对数据帧操作原理作出详细阐述。为了保证通信网络的传输性能,提出了一种冗余丢弃算法,并可在Windows系统下实现。实验表明:单网故障时,变电站通信网络不造成延迟,能实现无缝切换。PRP网络结构简单,具有较高的可靠性,良好的经济性,将成为智能变电站通信网络的主要研究方向之一。The principle of the Parallel Redundancy Protocol(PRP)in IEC 62439-3 is introduced.The basic structure of DANP and the principle of data frame operation are expounded in detail.In order to ensure the transmission performance of the communication network,a redundant discarding algorithm is implemented in Windows.The experiment shows that the substation communication network does not cause delay and can achieve seamless switching when single network fault occurs.The PRP network has the advantages of simple structure,high reliability and good economy,and will become one of the main research directions of the Intelligent Substation Communication.
